CS480

Correct pivot rotation by pressing arrow keys (as shown in working example program) Use keys other than arrow keys to change angle Either of the links does not rotate correctly	30  points -5 -15
Correctly redraw arm when window is resized  If the arm is scaled when window is resized but still works correctly	10 points -5
Change length of blocks  If changing length of blocks changes link angles unpredictably but mouse clicks still work with new lengths Link length goes negative	10 points -5 -5
Solve for angles that automatically move tip of green block to mouse location If works correctly in only some of the quadrants (linked to atan2 use error) If the program doesn’t work when link lengths are changed. If the click point too far from center hence unreachable case is not handled If the click point too close to center hence unreachable case is not handled	30 points -10 -10 -5 -5
Programming style (in line with the programming guidelines) Comments and boilerplate Variable names and indentation Efficiency. Are we recomputing some numbers that have not changed? Modularity and program structure. Do we have separate methods for separate tasks?	20 points -4 -4 -4 -4
Support arms made of three blocks  (extra credit)  Only works for fixed link lengths Each boundary case (too close, too far ) not handled	10 points -5 -2 each
